MOST DANGEROUS TOOLS

High Risk

The most dangerous OpenStudio MCP Server tools

Write · High apply_space_type_and_construction_set_wizard This tool creates or modifies data in the building energy model (space types and construction sets), which are reversible changes. Write · High convert_to_idf Conversion tools generate new files or data representations from existing models. Write · Medium copy_file File copying is a reversible Write operation (the original and copy both exist; no deletion occurs). Write · High save_osm_model The 'save_osm_model' tool creates or modifies OSM files by persisting changes to building geometry, HVAC systems, materials, schedules, and loads.

6 of OpenStudio MCP Server's 20 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control OpenStudio MCP Server

PolicyLayer is an MCP gateway — it sits between your AI agents and OpenStudio MCP Server, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "load_osm_model": {
    "limits": [
      {
        "counter": "load_osm_model_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_building_info": {
    "limits": [
      {
        "counter": "get_building_info_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Questions about OpenStudio MCP Server

How do I prevent bulk modifications through OpenStudio MCP Server? +

The OpenStudio MCP Server server has 5 write tools including load_osm_model, apply_space_type_and_construction_set_wizard, convert_to_idf. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach OpenStudio MCP Server.
